This month I am a little late for the December Cyber Attacks Timeline. In the meantime, I decided to collect on a single table the main Cyber Attacks for this unforgettable year.

In this post I cover the first half (more or less), ranging from January to July 2011. This period has seen the infamous RSA Breach, the huge Sony and Epsilon breaches, the rise and fall of the LulzSec Group and the beginning of the hot summer of Anonymous agsainst the Law Enforcement Agencies and Cyber Contractors. Korea was also affected by a huge breach. The total cost of all the breaches occurred inthis period (computed with Ponemon Institute’s estimates according to which the cost of a single record is around 214$) is more than 25 billion USD.
